Platform Engineer

ppWe’re building something that doesn’t exist yet: an AI immune system for humans. /ppThe Umanitek Guardian Agent protects people from deepfakes and digital impersonation by combining intelligence with systems built for verification and scale. /ppIf you’re excited by the idea of building reliable platforms and backend systems for agents that reason, not just predict, you’ll feel right at home. /ph3Role /h3pAs a Platform Engineer, you’ll build and operate the platform powering the Guardian Agent ecosystem. You’ll work across backend engineering and infrastructure, building production‑ready services while ensuring they can be deployed, monitored, and scaled reliably. /ppYour primary focus will be developing backend services, REST APIs, MCP tooling, and agent runtimes using Node.js and TypeScript. You’ll also own key parts of the platform layer: CI/CD pipelines, cloud environments, deployments, observability, and infrastructure automation. /ppThis is a hands‑on role where ownership and systems thinking matter. You’ll help ensure Guardian services are secure, scalable, observable, and easy for the team to evolve. /ph3Responsibilities /h3ulliBuild and maintain backend services, REST APIs, MCP servers, and agent tooling using Node.js and TypeScript /liliDesign and operate cloud infrastructure on AWS /liliOwn CI/CD pipelines, deployments, release workflows, and production environments /liliBuild and maintain containerized services using Docker and infrastructure automation tools /liliEnsure reliability through monitoring, logging, alerting, performance optimization, and security best practices /liliTroubleshoot production issues across application and infrastructure layers /liliCollaborate on architecture decisions around AI agents, decentralized systems, and scalable production infrastructure /li /ulh3Technical Experience /h3ulli4+ years of experience in Backend Engineering, Platform Engineering, DevOps, or Infrastructure Engineering /liliStrong Nest.js, TypeScript and Node.js experience building production backend services /liliExperience with REST APIs, Express, Nest.js, and microservice architectures /liliExperience deploying and operating production systems in cloud environments (AWS, DigitalOcean, or GCP) /liliStrong experience with Docker, CI/CD pipelines, and infrastructure automation concepts /liliExperience with monitoring, logging, and production troubleshooting /liliSolid understanding of databases, networking, Linux systems, and security fundamentals /li /ulh3Nice to Have /h3ulliFamiliarity with Turborepo and monorepo workflows /liliExperience with MCP tooling, AI/LLM applications, or agent-based systems /liliExperience with Docker or advanced container orchestration /liliExperience with Terraform or infrastructure-as-code workflows /liliExperience with distributed systems, event-driven architectures, or background workers /liliFamiliarity with decentralized systems or knowledge graph technologies /li /ulh3Tech Stack and Tools /h3ullibCloud: /b AWS (S3, EC2, RDS, EBS, Amplify; GCP - nice to have) /lilibInfrastructure: /b Docker, Terraform, Infrastructure-as-Code, automation tooling /lilibCI/CD: /b GitHub Actions /li /ulh3Why Umanitek /h3pWe’re early, lean, and ambitious. /ppYou’ll work directly with founders and researchers behind OriginTrail and Umanitek, helping build the foundation of AI safety infrastructure used by public institutions, enterprises, and individuals. /ppIf that sounds like your kind of hard — come build with us. /ppWe offer a market‑aligned salary, participation in the employee stock option pool, and clear opportunities to grow into senior and leadership roles as the company scales. /p /p #J-18808-Ljbffr
